Detailed explanation-1: -Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. They have a vascular system (used for the transportation of water and nutrients) that includes roots, xylem, and phloem.
Detailed explanation-2: -Independent of shape, the vascular tissue of gymnosperm leaves consists of axial xylem and phloem elements embedded in the characteristic transfusion tissue. This tissue is again bordered by a conspicuous bundle sheath which for a number of gymnosperms was described to have similarities to a root endodermis.
Detailed explanation-3: -Gymnosperms are a group of plants with the following unique characteristics: They do not have an outer covering or shell around their seeds and form naked seeds. They do not produce flowers. They do not produce fruits.
Detailed explanation-4: -They do not produce flowers. Seeds are not formed inside a fruit. They are found in colder regions where snowfall occurs. They develop needle-like leaves. They are perennial or woody, forming trees or bushes. They are not differentiated into ovary, style and stigma. More items
